STAMPING- INSTRUMENT.

Specification of Letters Patent.

Patented Jan. 21, 1908.

Application filed January 23. 1907. Serial No. 353.734.

To all whom it may concern:

Be it known that I, JOSEPH V. WEOK- BAUGH, a citizen of the United States of America, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements `in Stamping Instruments, of which the following is a specification.

My invention relates to the class of devices which, being actuated by hand, are employed to stamp impressions from rubber or metal type upon paper or other surfaces and has for its object to provide an instrument of the class named in which the maximum of simplicity, economy of construction and ease of operation shall be combined with durability, thorough practicability in use and great rapidity of action.

Further advantageous .characteristics of my construction will be disclosed at intervals in the following description, reference being had to the accompanying drawings in the various views of which like parts are similarly designated and in which Figure 1- represents a side elevation of the instrument, partly in section, Fig. 2- an underneath view thereof, Fig. 3- a fragmentary elevation similar to that shown in Fig. 1, the operating parts being shown in lowered position, Fig. 4- a central vertical section through the device, Fig. 5- a similar view of the instrument with the operating parts in the lowered position,- Fig. 6- a fragmentary underneath view of the apparatus, Fig. 7'- a fragmentary, central, vertical section of the instrument with its type-carrying plunger-frame in the lowermost position, Fig. 8- a fragmentary vertical section taken along a line 8 8, Fig. 4, Fig. 9- an enlarged fragmentary, under. neath view of the instrument illustrating the means employed to lock the' type-bars in place, Fig. 10- an enlarged section taken along a line 10-10, Fig. 9, showing the locking means in inverted position, Fig. 11-a fragmentary section through the plunger frame taken along a line 11-11, Fig. 10, Fig. 12- an enlarged section along a line 12-12,

Fig. 9, Fig. 13- a fragmentary view in perspective of a solid type bar, as used in the device, Fig. 14- a similar view of one of the type sleeves employed in the construction, shown in the assembly drawings, and Fig.

15- a fragmentary sectional view of the base and operating bars, showing a modified form of ink pad.

Referring to the drawings, the numeral 5 designates a hollow, preferably rectangular base, comprising the normally horizontal top plate 5a, the vertical sides 5 and the thereonto adjoining end plates 5d. A column or post 6, rigidly secured in central relation to the top plate, extends upwardly therefrom and projects into a longitudinal, cylindrical recess 7 formed in the operating handle 8 which is centrally secured upon a plate 9 by screws 10 orother suitable means. Column 6, projecting through an opening 11 in the plate into the recess, is surrounded by a elically coiled spring 12, the upper extremity of which is secured to the said column in proximity to its u er end, while its lowermost coil is held in fpuied relation to the plate 9 by means of screw bolts 18.

The numeral 14 designates the preferably rectangular plunger frame which, in practice, carries the type used in producing the impressions and which is composed of the parallel side bars 14EL and the therewith integpal end bars 14C.

. igidly secured onto the frame 14 at its corners are four posts 15 of equal length, which, extending upwardly through diametrically corresponding openings 16 in the top plate 5a of the base, are secured at their upper extremities by means of nuts 17 to the before named plate 9. The frame 14 and the operating handle being thus firmly connected in parallel relation to each other and the top plate of the base, are normally held in an elevated position when the frame is in engagement with the inner surface of the plate 5a, by action of the spring 12 and when by pressure upon the hand piece, the plunger frame is depressed, the consequent expansion of the spring will cause the operating members to return to their normal position, the moment the pressure is released.

Secured along the inner surface of the top plate 5a of the frame, and in parallel relation to the sides 5 are two strips 18, the inner off-set portions 18en of which, being spaced from the said surface, form guide waysfor the outer, longitudinal edges of a member 19 designed to supply ink to the type when the plungerframe is in its uppermost posil outer surfaces. Although the sleeves as tion. Member'lQ is composed of a metal plate 19"]L and a thereto secured pad 19Cmade of felt or other absorbent material and which being of lesser widththan the plate, permits the longitudinal edges of the latter to project within the before mentioned guide ways. A slot 5s in one of the ends 5d of the base exceeding the plate 19a in width, affords means to install or remove the' pad without disturbance to the other elements of the'A instrument.

The parallel end members 149of the plunger frame 14 are provided at their lower edges with a number of equidistant, semicircular notches 20, which afford seats for the cylindrical extremities 21 of a pluralityT of angular type bars 22. Members 14C are furthermore provided at their outer ends with downwardly ranging flanges 23 spaced from the adjacent end surfaces of the side bars 14a of the frame, which. being of greater width than the therewith connecting end members, extend beyond their notched lower edges. The seats thus provided at each extremity of the end members 14a are, in practice, occupied by the extremities of locking bars 24, which being provided with semicircular notches 24EL spaced to correspond with those in the plunger frame, will when positioned in engagement with the notched edges of the latter, secure the type bars in parallel relation to eachother and the side members of the frame. Bars 24 are hingedly secured to the plunger frame at one of their extremities by means of pins 25, which projecting through corresponding apertures in the flanges 23 and the bars 24, are screwed into threaded recesses in the adjacent ends of the side bars of the frame. The opposite ends of the locking bars are normally held in position by means of draw bolts 26 disposed in registering, diametrically equal bores 27, 28 and 29 respectively in the flanges 23, the therewith engaging ends of the bars and the adjacent portions of the side members 14a. The bolts when shot, are retained in position by coil springs 30, which being disposed within the recesses 29 engage their adjacent inner extremities and they may be withdrawn by manipulation of screw bolts 31 which being screwed into correspondingly threaded apertures in the bolts, project through slots 31a cut longitudinally in the end portions of the side members of the frame.

The type bars 22 may be made solid as shown in Fig. 13 or they may be composed of an angular core, Vthe ends of which are made cylindrical to occupy the seats in the end members of the frame, and a correspondingly shaped sleeve 32 which surrounding the angular portion of the core, carries the therewith integral type 33 uponv its shown in the drawings are preferably made rectangular in cross section, it should be understood that they may be composed of a greater number of sides, which to adapt thetype bars to the requirements of the operation of the instrument, should be of even number and arranged to produce a regular polygon. Sleeves 32 may be composed of two or more adjoining sect-ions 32a as is shown in Fig. 2, for the purpose of facilitating the changing of certain portions of the type such as a date or a name of. the day or month, or they may be made in one continuous piece, extending the full length of the angular portion of the core which it surrounds.

The type bars are provided at one of their cylindrical extremities, which extend beyond the corresponding end member of the frame, with a preferably integral toothed wheeler pinion 33a, the teeth of which equal in number the sides of the bars of which they form part. A narrow plate 34, slidably mounted upon lthe inner surface of the plate 5a of the base, by means of screws 35 extending through longitudinal slots 36, has a plurality of equidistantly arranged pins 37 which extending downwardly, project respectively alongside and in engagement with the pinions on the type bars. The slide 34 is retained inlits normal position, when the type in the plunger frame is in engagement projection or stud 40 arranged to engage the detent and carry it out of engagement with the sliding bar during the downward movement of the frame. A spring 41 secured to the base by means of a screw 42, in engagement with one of the extremities ofu the sliding bar, is arranged to impel the latter longitudinally for -thepurpose of projecting the pins 37 in the path of the teeth of the respective pinions as soon as the latter, during the downward movement of the plunger frame, have progressed beyond the lower extremities of the pins, and the detent 33 has been released from contact with the slide. Spring dogs 43 secured upon the outside of the frame in the path of opposite edges of the late 9, are designed. to secure the plunger Frame and the therewith connected parts against retrograde motion when for the purpose of repairs or interchanging of type sleeves, the handle has been brought to its lowermos't position as illustrated in Fig. 7. In place of having one common inkpad to ink the type on the various bars in the plunger frame, a plurality of smaller pads 44 provided with diierent'colored inks, may be secured in parallel order upon the late 19a of member 19, as shown in Fig. 15, for thepur-l in the so-called se inking stamps, the time occupied in reversing the position of the type to bringv it in contact with the ink pad, may be considerably reduced by alternately supplying one of the sets with ink and employmg the adjoining set to produce the impression. With this object in view the four sides of each type bar are provided with identical type so that no matter which side is brought in contact with a surface, the impressions are at all times alike. When the base of the instrument is placed upon a fiat surface and the handle is depressed, the lowermost series of lines of type forming part of the several type bars, are brought in contact with the said surface and the characters of which it is composed are impressed thereupon. During the downward movement of the plunger frame, the stud 40, as hereinbefore explained, by engaging the detent 38, released the sliding bar 34 so that the moment the pinions were brought below the lower extremities of the pins 37, the latter were projected in the path of their teeth by action of the spring 41,

with the result that during the return stroke of the plunger frame, the said teeth coming in contact with the extremities of the pins, will cause the rotatable type bars to describe a quarter of a revolution and subsequently impel the sliding bar to reassume its original position before the uppermost type engages the inkpad. It will thus be observed that, after an impression has been made from one of the series of type, the lines on the adjoining surfaces of the bars are brought in contact with the inkpad and that the type which was supplied with ink prior to producing the said impression, is simultaneously brought to the lowermost position, in readiness to be impressed upon the surface. A

. s the mode of securing and interchanging the type sleeves and the purpose of the retaining dogs as well as the manner of securing and renewing the inkpad have been referred to at intervals in the course of the foregoing descri tion, further explanation of the operation ol these parts of my invention is omitted.

Having thus described my invention what I claim is 1.
